I'll make a very lame attempt at bastardizing how HDCP works to at least try and get the general idea quickly explained. Others can come correct me where I'm wrong or missing things, but hopefully this will help you get the jist of things... First, read a bit of this. So HDCP-compliant things can be either software or hardware. Either way, it's supposedly unhackable. While NOTHING is unhackable, think of this being about as unhackable as AES256-based encryption (i.e. it realistically ain't gonna happen), UNLESS they screw something up royally (and it has happened, but usually HDCP tends to be fairly trusted as being "secure"). So how this COULD apply to the phone (I have NO idea if there is ANY HDCP compliance in it at all!) is that HDCP-protected content that you download could be read by HDCP-compliant software that works with HDCP-compliant chips in the phone that work with an HDCP-compliant display. If this is the case, then you could download HDCP-protected and display it on screen. However, rooting your phone (or custom ROMs) doesn't give you access to the content because your software couldn't decrypt the downloaded content. Also, because your software breaks the chain of HDCP-compliant things, the other HDCP-compliant things won't work with your software in the context of HDCP (but will for non-protected use). Now consider your HDMI port. HDMI ports are potentially HDCP-compliant, but only if all of the hardware associated with them are also HDCP-compliant. IF any of that hardware is not HDCP-compliant, then your HDMI port instantly becomes useless for HDCP-protected content. As such, you could never display HDCP-protected content onto a TV from your Droid X, if this were the case. Now keep in mind, I don't think anybody knows if there's any HDCP compliance to this phone at all. But I'm just saying, if we say "it can be done with anything if we root it", that we are STILL making assumptions, and one such assumption is that HDCP-protected content is not something we're trying to work with.
